It will be noted that the device 3 is applied to existing old style 60 tion which consists of a stem type hand grip 16 being positioned on member 17, which member 17 is spaced paddles by an attaching post shown at 4 which allows longitudinally on stem ‘2 and perpendicular thereto. a bolt 13 to pass therethrough and also through stem 2. FIGURE 8 shows a top view of the same embodiment FIGURE 3 shows the position the device could take of FIGURE 7. It can be clearly seen that the hand ‘grips relative to the plane of the blades so as to effect the proper angle when the blades enter the water on the 65 16 are rotatable about the longitudinal axis of the posts 17, which posts 17 are perpendicular to the paddle stern. paddling stroke.
